The first NATO Advanced Study Institute on Nitrogen Ceramics held in 1976 at Canterbury came at a particularly significant moment in the development of this subject. The five-year period, 1971-75, had been an especially fruitful one in very many respects for work in the areas of covalent materials in general, and of the nitrides in particular. The Institute was therefore able to cap ture fully the spirit of excitement and adventure engendered by the outputs of numerous national research programmes, as well as those of many smaller research groups, concerning ceramics potent ially suitable for applications in a high temperature engineering context. It reflected accurately the state of knowledge with respect to the basic science, the powder technology, and the prop erties of materials based on silicon nitride and associated syst ems. The Proceedings of the Institute thus provided a good record for workers already in the field, and a useful textbook for new comers to the subject of nitrogen ceramics. The Canterbury Advanced Study Institute had a valuable educ ational and social function in bringing together for two weeks a large proportion of those workers most closely involved at that time with the nitrogen ceramics. The atmosphere of this meeting, providing both intensive discussions and informal contacts, made a lasting impression on the participants, and inevitably the question was raised of whether, and when, a second Advanced Study Institute might be held on this subject.

The nitrides and carbides of boron and silicon are proving to be an excellent choice when selecting materials for the design of devices that are to be employed under particularly demanding environmental and thermal con- tions. The high degree of cross-linking, due to the preferred coordination numbers of the predominantly covalently bonded constituents equalling or exceeding three, lends these non-oxidic ceramics a high kinetic stability, and is regarded as the microscopic origin of their impressive thermal and mechanical durability. Thus it does not come as a surprise that the chemistry, the physical properties and the engineering of the corresponding binary, ternary, and even quaternary compounds have been the subject of intensive and sustained efforts in research and development. In the five reviews presented in the volumes 101 and 102 of "Structure and Bonding" an attempt has been made to cover both the essential and the most recent advances achieved in this particular field of materials research. The scope of the individual contributions is such as to address both graduate students, specializing in ceramic materials, and all scientists in academia or industry dealing with materials research and development. Each review provides, in its introductory part, the chemical, physical and, to some extent, historical background of the respective material, and then focuses on the most relevant and the most recent achievements.

The investigation of multi-component complex systems composed of oxides, nitrides, and carbides has intensified in the last few years. Phase Diagrams in Advanced Ceramics reviews some of the recent advances inthe understanding of these composite systems, providing insight into how phase diagrams can be utilized in the fabrication of whiskers and ceramic-matrix whisker-reinforced ceramics. Phase relations and sintering information is reviewed for transparent polycrystalline oxides. Phase diagrams are discussed to predict alkali oxide corrosion of alumino-silicate references. - Understanding the development, manufacture, and use of complex, multi-component ceramic materials composed of silicon nitride-metal oxides-nitride-carbide systems - Development and use of whisker and whisker-reinforced ceramics composed of materials such as alumina, silicon-nitride, silicon carbide, and directly solidified eutectic ceramics - Application of phase diagrams to the production of advanced composites such as alumina-matrix, zirconium diboride and titanium, hafnium, zirconium, carbides, and borides - Phase chemistry in the development of transparent poly-crystal and oxides, including yttria, alumina, and magnesium aluminate - Improvements concerning the knowledge of complex multi-component materials composed of oxides, nitrides, and carbides, and knowledge of how to fabricate composite materials containing whiskers and ceramic hosts - New developments in making transparent ceramic materials

Despite the significant progress, which has been made in developing of ceramic materials desired for engineering applications, their mass production is still not on expected level. Among the key factors hindering higher exploitation of these materials the problems in processing were identified. The processing comprises powder production, mixing techniques, forming, and sintering. All of them are equally important and all of them can introduce defects into the material. Besides improvement in processing, the properties of ceramic materials can be considerably improved by the creation of composites. Composites formed at micro or macro level are able to form more flaw-tolerant material. Considerable research activities, working on above mentioned phenomena are in progress at industrial laboratories as well as other research centres. This volume presents the contributions to the Advanced Research Workshop "Engineering Ceramics '96" with 65 participants from 21 countries held on 12th - 15th May 1996 at Smolenice Castle, Slovakia, the conference site of Slovak Academy of Sciences. The book covers research activities on engineering ceramic materials and gives an overview with respect to recent developments.

Conferences on technical and engineering ceramics are held with increasing frequency, having become fashionable because the potential of ceramics in profitable growth industries is an urgent matter of considerable debate and discussion. Japanese predictions are that the market value of ceramics will grow 10 at about 10% per annum to reach at least $10 by the end of the century. Seventy per cent of this market will be in electroceramics, applications for which include insulating substrates in integrated circuits, ferroelectric capacitors, piezoelectric oscillators and transdu cers, ferrite magnets, and ion-conducting solid electrolytes and sen sors. All these are oxides, and so are excluded by the title of the Limerick Conference. Why 'Non-oxide'? The other major ceramics potential is in struc tural engineering components and engine applications. Here, the greatest impetus to research and development has been the attempt to produce a ceramic gas turbine. Heat engines become more efficient as their working temperature increases, but nickel-base superalloy en gines have about reached their limit. Compared with metals, ceramics have higher strengths at high temperatures, better oxidation and corrosion resistance, and are also less dense. In general, ceramics have better properties above about 1000°C except in one respect-their inherent brittleness. The work of fracture is therefore much smaller than for metals and so the permitted flaw size is also smaller.
